No ideas, eh? Sometimes I have 2 or 3 of these processes running at a time, each using 70-110% of CPU. They run for up to to 2 or 2.5 minutes and then disappear. I'm sure these are the cause of my higher than usual server loads.

Just curious... do you have mailscanner installed yourself or are you using chirpy's service? Also, do you know what version of spamassassin you are running? I'm running 3.20 but I know that vanilla cpanel setups on 11 are being held back to 3.18. I've read some of the threads on that and don't seem to be having any of the problems that people are having with 3.20, but I have noticed a few no scoring, "SpamAssassin not cached, timed out" messages.

I'm wondering if there's a relationship to these things. Chirpy, do you have any thoughts? I didn't notice anything on your forums or blog along these lines.

Same for my mailscanner install. I think (not really sure) that may be why my spamassassin is not being held back to 3.1.8 like most v11 users. I'm not sure if that's any kind of problem, just an observation.

ive also got these issues, i believe that mailscanner uses mysql, so the two having high loads are connected.

by default mailscanner does not use mysql. Only if you use chirpy's package with mailwatch that it will use mysql. Let's hope chirpy have some answer to this problem because so far I see this upgrade to 11 is a little disastrous. I am withholding my upgrade until all these problems are solved especially the spamassassin and exim changes that cpanel team did.

If you do not need persistent connections, then change this to "Off" and save, then reboot the httpd server (Apache). You can now edit the php.ini file in WHM under "Service Configuration" but to get to this setting you must go to the Advanced Configuration. You will still need to reboot Apache after this.

Making the changes in #2 and #3 made incredible speed changes in my VPS's. I have to thank Chirpy for these two bits of advice somewhere in posts in this forum. And for his great service which I could not live without!!!!

Hope this helps - I've been pulling my hair out over why my servers seemed to be set up the same way, but one was extremely fast, one was OK and one was extremely slow - they all had differences in these settings and the fastest one was the newest one and was set up originally with the maildir format while the other two were holdouts until this mornings when I woke up to hundreds of emails stuck in each queue. Even after the conversion the one was still very slow until I switched from clamav to clamavmodule and the CPU load dropped from around 1.9 to 0.3 and has stayed there all day.

have you tried turning off virus scanning? See if virus scanning is causing the load.

Hi abubin,

I haven't tried that yet. I know it will reduce the load and will in a last ditch attempt. That said, I've been running with my current setup and a manageable server load for a year or more. The only thing that has changed (AFAIK) and has pushed the server load high is the update to cp v11

Disabling virus scanning didn't make very much difference. Disabling mailscanner altogether made a big difference though. Obviously a little too extreme. I'm trying a few suggestions from configserver support to see if I can get some relief and will post back here if anything is found. BTW... I have run Mailscanner in debug mode and that didn't provide anything helpful either.

I'm beginning to suspect the problem is a result of a combination of things, of which mailscanner is only one. Perhaps my OS (CentOS 3.8) or my kernel (2.6.17.11) are just too old for cp 11. Who knows. My memory seems OK.

I feel too far committed to cp 11 to go back, but something since the update has made my average server loads increase 200-400% It's discouraging.

Nothing really concrete in terms of a solution or single answer. I went through all sorts of stuff like force reinstalling of exim, spamassassin, mailscanner, and so on. That helped, but not enough. Then tweaked a few things in mysql and apache also that although unrelated, did help to optimize the server. In general, things are back to a more acceptable state.

Overall though, my avg server load is still at least double what it was before cp 11. I can no longer blame this strictly on mailscanner, I have no idea what it is. It doesn't seem to be hugely widespread, but I don't think I'm the only one with such higher avg server loads recently.
